PHILADELPHIA, "PENNSYLVANIA, A COBTORATION OF MECHANIS For. MAKING LINOLEUVM."

Application filed m ster 2.1920. SeriaiNo; 421,376.

To aZZwhom itmag) concern: I Be it known that LJO N TAMBERLIN, a citizen of the United States, residing in the city of Philadelphia. county of Philadelphia. and State of Pennsylvania, have" in vented an Improved Mechanism for Making Linoleum, of which the following is a specification. r

My improved mechanism relatesto the manufacture of granite linoleum or linoleum made from mixtures of finely divided com positions variously colored and it is dethe colored composition upon a" backing fabric rapidly and efiiciently so as to produce a desired effect and a superior product. The inventionischaracterized by the combination with a vertically movable perforated. or apertured templetund er which a backing fabric is movable intermittently, of composition depositing means comprising a spreader adapted for moving over the term plet and forcing therethrough composition carried thereby.

The characteristic features of the invention are embodied in the machineset out in the following description and the accompanying drawings in illustrationthereof.

In the drawings, Fig. 1 is a side elevation of a machine having improvements of my invention applied thereto; Fig. '2 is a plan view'of deposits of sections of composition prior to pressing; Fig. "3 is a broken elevation on an enlarged scale of a section of the construction shown in Fig. 1 in illustration of detai s of the spreading and depositing mechanism; Fig. dis a broken longitudinal section taken through the construction shown inFig. 3, and Fig. 5 is a broken -sec tional plan view of the spreading and 'depositing mechanism. I

The machine comprises the" frame 1. hav ingthe journalled end drums'2 which carry an endlesspin band 3, the pin band being operated to move the burlap or woven back-,

The composition to be spread and deosited upon the burlap between its'step y step movements is held in the hoppers 5 which are supportedby the frame at the desired intervals along the path through whichthepin band carries the backing, the hoppers being provided with the respective rotary valves 6 having measuring pockets adapted for delivering the composition therefrom in theamounts desired. I

Spreaders 7,]being plates having oppopositely extending arms 9 through which passesa shaft lOhaving its" ends journalled in the slides 11; Theseslides are movable along the guide bars 12 extending longitudinally of the machine under the respective hoppers 5, so that the contents of the latter can be delivered by the respective valves 6 to the respective spaces between the spreaders 7 when positioned below the hoppers. Cross bars 13 connect the ends of the bars'lQ and thetops of the uprights 14 which are fixed thereto, with'the side bars 15 extending longitudinally of thelmachine'. Serrated bars 16, parallel'to the bars 12,

sitely deflected tops 8; are provided with opare fixed to the bars 13 by the legal? de- 3 pending therefrom. Side bars "18 and cross bars 19, forming boxes o1"e11closures. have their connected ends fixed in ad ustab e relatlon to the bottoms of the uprights 14; by

the bolts 20which pass through. slotsQl in the corners ofthe boxes and through the uprights. Plates 22ers fixed at the bottoms and the respective ends of the enclosures formedby the parts 18 and 19, and templets 23; being coarse wirescreens of rectangular mesh as shown, are fixed along their rectangular edges to vth bars and the The parts 22 and '23 with their direct core as also the burlap 4', and the shafts iO are rocked in and reciprocated transversely by means of the slides 11 which move along the guides12, to operate the Spreaders 7 between thebars 19 within the respective enclosures formed thereby with the b'ars18. Thereby the composition delivered from the hoppers 5 to the space between the complementary Spreaders is carried between the fplates 22' over the teniplets 23, through which 'nection are operated above the pin .band'Q,

such composition is spread and deposited upon the section of the now stationary burlap beneath it.

The actions of the spreaders 7 are controlled by the engagements of studs 24: on

their arms 9 with arms 25 fixed in adjustable relation on the rock shaft 10, the rocking movement of the latter being limited by yokes 26 fixed thereon and having bifirn cations adapted to be engaged alternately by the studs 27 fixed to the slides 11 upon "parallelbars 31-are movable longitudinally through depending parts of the slides 11 and whoseouter ends are provided with rollers which run along the irregular tracks or bars 16, provided with staggered serrations.

The shafts 10 are rocked and translated by cranlrarms 33 which are coupled together by the rods 34, the arms beingrocked by the action of a rod 35 and an actuating lever 36 connectedthereto. The lever is fixed to ashaft 37 journalled in the bearings 38 and rocked by the arms 39 fixed thereon, the latter being provided with rollers 40 which act in the cam ways 41 of reciprocating bars 12 which are guided bythe rollers 43 and tt. The bars 4:2 are reciprocated by the pitmen rods 45 which connect them with the spur wheels 46 drivenby the gearftrain 47. v

Slides 4:8, fixedto and depending from the bars 15, which normally rest on struts 15, are movable in the vertical guides 49 fixedto the frame, to elevate and lower the parts connected therewith, for the purpose of elevating the parts 22 and 23 when the burlap '.with the composition deposited thereon is ,to be advanced and of lowermg such parts for the performance of the spreading and depositing operations. Simultaneously with the elevationzof the-templet and its connections, the space betweenthe Spreaders '7 rep;-

istfil'ing with the hopper 5 and the part22, ,the valve; 6 1s operatedand composition s delivered between the spreaders by the action of a weightedlever 6 through. a pawl 6 upon a ratchet wheel 6 which turns the valve, the

lever being retracted upon the lowering of the tcmplet by the chain 6 connectingsuch leyer withthe part 15.

- Rollers 50 on thebottoms of the slidestl act inthecam ways 51 of the bars 42 whereby the vertical movements of'the slidesare ef- 1 fected, 1

( The slides 48 with their connections when the backing is at rest. But when the agitating, depositing and spreading mechanisms are at the limits of their movements and at rest over the plates 22, the rollers 50 are acted upon the cams 51 to elevate the slides 328 with the parts connected therewith. including the templets 23, during the periods when the backing with the deposits thereon are moved forward to receive subsequent deposits.

When the tem'plets'23 are lowered and the cranks 58'are operated, tliesh'afts'll) are rockedto the permitted by the engage ments of the yokes 26 with the studs 27 and thefnrther movements of such shafts translate them laterally, the slides 11 moving along the guides 12. As the shafts 10 are rocked, the-arms 25, extending therefrom in the direction of the operating thrust, are elevated and act throughthe studs2aion the arms 9 to elevate thecorresponding spreaders The arms 25 extending oppositelyor rearwardly from the direction oflateral movement of the shafts are simultaneously depressed and.withdrawn from the corresponding studs 24 on the rearwardly extendins: arms. 9 tov permit the fcorresponding preaders Tto fall into position for engaging the parts 22 and 23. I i-is theshafts IO -with the parts carried thereby are translated over the templets 23, the actions of the serrated bar-s19 upon the rollers 32 reciprocatethe shafts29 longitudinally and the fingers 2S laterally in the composition which is being carried between the complementaryflspreaders 7' over the templ-ets 23-}. Thereby ahdesired amount of the compositioiris worked through the templets and deposited on the backing lying below them. the rear spreaders 7 scraping the tops of the templets and carrying forwanl the composition above the same. 7

, lilhen the rear spreader-s have passeil over the templets, the composition between complementary spreaders resting upon when, the continued movement of the operating mechanism rev c es the spreading and depositing mechanisms which areithereupon carried over the templets in the opposite direction, with resu ting supplementary actemplets upon the backing so as to effect the desired deposits thereon;v e

When the spreading mechanisms {have reached the limits oftheir reverse movements, the cam bars 42 act upon the rollers 50 to move the slides 48 upwardlygthe'slides acting th-rough thebars 15 and the dependmg parts for the purpose of elevating the templets andpermitting the burlap with the deposits thereon tobe moved forward and bring succeeding sections thereof under the templets 'for the reception of succeedingdeposits. The fabric having-been ad mneedthe desired CllStSJlCQYthmovement of the-cam bars permits the templets to fall and'the succeeding deposit of" composition spread thereon.

The backing with the deposits required for coating it is fed through a press Sflwhi'ch consolidates the composition and effects its adhesion to the backing."
